    • A connection assistance apparatus avoids unauthorized access and DoS attacks, prevents a performance degradation from occurring, and does not need to recognize different connections to gateway apparatus. An authenticating unit authenticates the validity of a terminal by checking if the terminal is a valid terminal capable of communicating with a gateway apparatus according to IPSec in response to a request from a user who owns the terminal. If it is judged that the terminal is a valid terminal, then a preshared key generating unit generates a preshared key for the terminal and the gateway apparatus, and a firewall opening instruction information generating unit generates firewall opening instruction information to open a firewall of the gateway apparatus. A transmitting unit sends the preshared key to the terminal and the gateway apparatus and sends the firewall opening instruction information to the gateway apparatus.
    • 连接辅助装置避免未经授权的访问和DoS攻击,防止性能下降发生,并且不需要识别与网关设备的不同连接。 认证单元通过根据来自拥有终端的用户的请求,通过根据IPSec检查终端是否能够与网关设备通信的有效终端,来验证终端的有效性。 如果判断终端是有效终端,则预共享密钥生成部生成终端和网关装置的预共享密钥,防火墙开放指示信息生成部生成防火墙开放指示信息,以打开网关的防火墙 仪器。 发送单元将预共享密钥发送到终端和网关装置,并将防火墙打开指示信息发送到网关装置。

    • A communication device collects encrypted packet data passing through the communication device. The communication device extracts parameters required to generate a decryption key used when the collected packet data is decrypted. The communication device notifies a key managing device of the extracted parameters. The communication device acquires the decryption key, generated by the key managing device using the parameters of which notification has been given, from the key managing device. The communication device decrypts the collected packet data using the acquired decryption key and analyzes the decrypted packet data. The communication device extracts profile information from the analyzed packet data. The communication device transmits the extracted profile information and network information related to a network through which the encrypted packet data passes to a communication log device as a communication log.
    • 通信装置收集通过通信装置的加密分组数据。 通信装置提取生成在收集的分组数据被解密时使用的解密密钥所需的参数。 通信装置向密钥管理装置通知所提取的参数。 通信装置从密钥管理装置获取由密钥管理装置使用已经给出通知的参数生成的解密密钥。 通信装置使用获取的解密密钥解密收集的分组数据,并分析解密的分组数据。 通信设备从分析的分组数据中提取简档信息。 通信装置将提取的简档信息和与加密分组数据所通过的网络相关的网络信息作为通信日志发送到通信日志装置。
